GUY GIFTS: So you can't afford a thousand-inch HDTV. What now? South Moon Under is offering 20 percent off all menswear through Sunday, Dec. 12 with online code MENS20. That includes footwear, accessories and even swimwear (and if you're spending the holidays in the Caribbean, we want to let you know right now that we hate you just a little). You'll save on everything from North Face -- we can't think of a dude who wouldn't be OK with that -- to edgier looks, like the Jedidiah Commerder Jacket. GET IT: South Moon Under, 2700 Clarendon Blvd., Arlington; Wildwood Center, 10247 Old Georgetown Road, Bethesda, or online.
